Home -> Community -> Mailing Lists -> Oracle-L -> Anybody have an idea why this is happening?
I need to compare "identical" databases across two instances. I've set up a MID instance to do the heavy lifting and not impact our production. But this particular form of querying via link A with a sub-query via link B kills the session.
middleman_at_mid> SELECT ADR_DTF_ID FROM ADDRESSES_at_IHP WHERE ADR_DTF_ID IN
2 (SELECT DTF_ID FROM ADDRESSES_at_EID1, DETENTION_FACILITIES_at_EID1
3 WHERE DTF_ID = ADR_DTF_ID (+)
4 AND ADR_DTF_ID IS NULL)
5 /
SELECT ADR_DTF_ID FROM ADDRESSES_at_IHP WHERE ADR_DTF_ID IN
*
ERROR at line 1:
ORA-03113: end-of-file on communication channel
On the other hand
middleman_at_mid> SELECT ADR_DTF_ID
2 FROM ADDRESSES_at_IHP
3 WHERE ADR_DTF_ID NOT IN (SELECT ADR_DTF_ID FROM ADDRESSES_at_EID1) ;
no rows selected
works just fine.
I can work around it but curiosity is driving me to distraction.
